  2. Outline • Wavelengths monitoring solutions • Requirements for wavelengths monitoring • Lambda Monitor software • Deployments of Lambda Monitor • Conclusion • Future development of LM AICT 2008, Athens, Greece, 8-13 June 2008 2

  3. Motivations • Network providers are moving towards the optical networks • Researchers are increasingly using dedicated optical paths for creating high speed network connections • Optical paths may span over multiple administrative domains and different vendors • Open source is a key for research purposes AICT 2008, Athens, Greece, 8-13 June 2008 3

  4. Wavelengths Monitoring Solutions (1) • Only few monitoring tools available for wavelengths monitoring • Vendors of optical systems have created vendor-specific tools – such as for example • ADVA FSP Management Suite • FSP Element Manager • FSP Network Manager • FSP Network Planner • Alcatel • Alcatel 1320 Craft Terminal • Alcatel 1352 Compact Manager AICT 2008, Athens, Greece, 8-13 June 2008 4

  5. Wavelengths Monitoring Solutions (2) • Biggest limitations and disadvantages in the mentioned before vendor-specific tools • Lack of free and open source software • Functionality dedicated for network operators only (not for wavelengths’ end-users) • Lack of integration for multiple vendors and various equipment platforms AICT 2008, Athens, Greece, 8-13 June 2008 5

  6. Requirements for Effective Wavelengths Monitoring • Assist and speed up the work of NOC • Integrated user-friendly view of wavelengths • Easy to identify alarms and localise faults • Detailed informationfor each wavelength (configuration parameters & physical characteristics) • Free & open source software AICT 2008, Athens, Greece, 8-13 June 2008 6

  7. Lambda Monitor Overview (1) • SNMP-based (read-only polling) • Simultaneous monitoring of many wavelengths used by user’s group • Real-time notification of current problems occurring in the optical network • Integrated view of wavelengths by means of graphical web-based interface • Detailed information about the physical characteristics of individual wavelengths AICT 2008, Athens, Greece, 8-13 June 2008 7

  8. Lambda Monitor Overview (2) • Implementation • PHP5 • XHTML • CSS • JavaScript • Integration with perfSONAR multidomain monitoring system developed in GÉANT2 • Released under GNU GPL version 3 AICT 2008, Athens, Greece, 8-13 June 2008 8

  9. Lambda MonitorArchitecture AICT 2008, Athens, Greece, 8-13 June 2008 9

  10. LM Server Architecture AICT 2008, Athens, Greece, 8-13 June 2008 10

  11. User Interface • Hierarchical user interface – one simple view for complex network and top-down approach to see more detailed information if needed • Three levels of GUI (called layers) • Lambdas layer • Devices layer • Parameters layer • Current and historical alarms browsers AICT 2008, Athens, Greece, 8-13 June 2008 11

  12. Lambdas Layer • Current status of monitored wavelengths (end-to-endview) • Possible state of the wavelengths: OK state - lambda circuit works OK without any alarms Warning state - occurs when some warning type alarms are present in the lambda circuit Critical state - occurs when any of critical alarms appeared in lambda circuit Unknown state – lack of information about lambda circuit (snmp agent unreachable) AICT 2008, Athens, Greece, 8-13 June 2008 12

  13. Lambdas Layer Interface AICT 2008, Athens, Greece, 8-13 June 2008 13

  14. Devices Layer • Current status of the interfaces terminating selected wavelength on DWDM devices • Possible states of the interfaces: no alarms on device’s interface warnings on device’s interface critical alarms on device’s interface lack of information about interface (snmp agent is unreachable) AICT 2008, Athens, Greece, 8-13 June 2008 14

  15. Devices Layer Interface AICT 2008, Athens, Greece, 8-13 June 2008 15

  16. Parameters Layer • Current values of various monitored parameters on selected device’s interface in the form of graphical tables • Detailed information about many parameters which determine and impact the operation of wavelengths AICT 2008, Athens, Greece, 8-13 June 2008 16

  17. Parameters Layer Interface AICT 2008, Athens, Greece, 8-13 June 2008 17

  18. Alarm Browsing • Current alarms browser • Enables viewing of alarms that currently occur in the monitored wavelengths • Alarms history browser • Presents all the alarms that occurred formerly AICT 2008, Athens, Greece, 8-13 June 2008 18

  19. Alarm Browsing Interfaces Current alarms Alarms history AICT 2008, Athens, Greece, 8-13 June 2008 19

  20. Deployments of LM Software Successfully deployed in twoNRENs • PIONIER - in Poland • Optical architecture of the network embraces 21 ADVA FSP 3000 devices • Monitors 24 of the 10Gbit/s wavelengths used in the PIONIER national backbone • HEAnet - in Ireland • Optical architecture of the network consists of 17 ADVA FSP 3000 devices • Monitors 14 of the 10Gbit/s point-to-point wavelengths used in the HEAnet national backbone AICT 2008, Athens, Greece, 8-13 June 2008 20

  21. Conclusion • Optical network monitoring is very important and requires dedicated monitoring solutions • Vendor-specific commercial applications dedicated for operators only on the market • LM - open source tool with web-based GUI for both NOCs & users for wavelengths monitoring • Fast, exact and user-friendly localisation of faulty wavelength circuits and possible failure reasons • Successful tests and deployments • Current development of LM under GÉANT2- JRA4 AICT 2008, Athens, Greece, 8-13 June 2008 21

  22. Future Development of LM • Main propositions for future LM development in the Emanics project • Parameters archiving (historical values of monitored parameters in the form of charts) • Monitoring and notification of configured thresholds exceeding • Mail notification of current alarms occurring in monitored wavelengths • Full system documentation & install packages for various distributions with user guide AICT 2008, Athens, Greece, 8-13 June 2008 22
